Title: Optical recording and reproducing device
IPC: G11B21/10
Filed: 1992-03-27
Abstract: PURPOSE:To reduce the control output deviation of a two step type position control system and to correct a servo error suppression residual difference by detecting and controlling the mechanical characteristic change of a galvanomirror structure being a precision position control means by an external circuit. CONSTITUTION:When the mechanical neutral position of a galvanomirror displacement mechanism 5 is different from a track servo target position in signal 111, a control deviation detection output signal is read directly by a deviation signal processor with an A/D converter 31. In such a case, a displacement position is displayed by using the peak value of a servo error signal 202 or the time mean value of the servo error signal 202. Then, since the gain and the position control constant of the two step type position control system are known, a servo error amt. caused by the deviation of a mechanical neutral point is calculated by a fixed calculation procedure.
